NetworkManager and GPS Support

[Jean-Louis Dupond <jean-louis dupond be>]

Hi

Today i've been working on implementing GPS support for my HSPA modem.
The implementing itself is not that hard, but there are some issues.

The code (its NOT complete) can be found on 
http://ubuntu.dupondje.be/modemmanager.diff

Now I got some question about then next steps.

To enable the GPS, you need to send "AT*E2GPSCTL=1,5,1" to /dev/ttyACM1.
After this "AT*E2GPSNPD" can be send to the device where you want the 
GPS messages from.
This can be send to /dev/ttyACM1, but then you can't send other commands 
to that device anymore.

But the device has also /dev/ttyACM2 that is made for this.
We can send "AT*E2GPSNPD" to that device, and then /dev/ttyACM2 will 
send all the GPS info.

Now the issue is how to handle the ttyACM2 device.
As there doesn't seem to be a command to ask if that device is the GPS 
device.

Now it gets ignored by modemmanager.

Any idea's on how I could handle this?


Thanks in advance!
